We introduce a natural cryptographic functionality called functional re-encryption. Informally, this functionality, for a public-key encryption scheme and a function F with n possible outputs, transforms (“re-encrypts”) an encryption of a message m under an “input public key” pk into an encryption of the same message m under one of the n “output public keys”, namely the public key indexed by F (m). In many settings, one might require that the program implementing the functional reencryption… CONTINUE READING
